This is a great deal on long-lasting batteries with 3 ways to charge charging included. I can't speak to how long they last yet because I haven't had the chance to run one out completely; however, based on previous comments, it looks like they will certainly deliver. I highly recommend this deal. The package arrived quickly and the packaging was excellent.

Just the right size for the cameras in the items description.

I video events and these batteries eliminate one of my greatest fears - having to change batteries during an important moment. I get about 150 minutes on a bettery.

I have two Canon video cameras that use the "BP" style batteries, and these batteries from Kastar work correctly with one of them. It works with the Vixia camera, but doesn't communicate with my XA-10. Without "communication", the camera can't display the battery level and shows a question mark instead. The battery still powers the camera just fine, you just can tell how much power is remaining.The batteries work perfectly with the more consumer oriented Vixia camera, so no complaints there. I have other "generic" batteries for these cameras that don't have any communication issues, so I'm not sure why these particular batteries don't work with the XA-10. To be fair, they don't specifically mention the XA-10 as compatible in the description, but does mention the XA-13 as being compatible. I thought they used the same battery tech, but I may be wrong.In any event, the batteries do provide power to both cameras and the package comes with a charger, which is a nice inclusion.

The media could not be loaded. Great Quality for batteries. Long life on camera, just as good as original batteries when they were new. Nice and snug, they are slightly longer. Check out the video for comparison between cannon one and this.

Excellent. Just as described.

These batteries gave my 15 year old Canon Vixia HG20 new life. They work seamlessly with my camcorder and last much longer than the original battery did. They come with a charger that includes a 12v car adapter and a European outlet adapter. I have not tried charging them while installed in the camera, I'll update this review when I do. I recommend these to anyone trying to give an old camcorder new life.
